Grade 4 Time Worksheets — 24 Hour Clock and Duration
Fourth grade brings the two things that make time genuinely useful: answers in hours and minutes rather than a long list of minutes, and the 24-hour clock that timetables actually use. Grade 4 offers seven separate sheets — Elapsed Time in Hours and Minutes, The 24-Hour Clock, Later Times, Earlier Times, Two-Step Times, Units of Time and Calendar and Dates.
Elapsed Time in Hours and Minutes asks how long a span lasts and expects an answer like "3 hours 25 minutes". The 24-Hour Clock has a page of its own for readings such as 14:20 and 17:05. Later Times adds a duration to a clock time and, on its upper levels, runs past noon or past midnight. Pick the sheet and level, set the number of questions, and print with or without the answer key. The shareable link reproduces the exact sheet, which is handy for setting the same timetable practice across a whole class.

Each one generates a different kind of question, with its own three levels and answer key.
- Elapsed Time in Hours and MinutesWork out how long something lasts, in hours and minutes.
- The 24-Hour ClockChange times between the am/pm clock and the 24-hour clock.
- Later TimesCount forward from a time to work out when something finishes.
- Earlier TimesCount back from a time to work out when something started.
- Two-Step TimesWork out the time after two activities, one straight after the other.
- Units of TimeConvert between seconds, minutes, hours, days, weeks, months and years.
- Calendar and DatesDays of the week, months of the year and working out dates.
What each level generates
Grade 4 elapsed time in hours and minutes — the exact skill behind each difficulty setting, straight from the generator.
- Level 1Longer spans
- Level 2Crossing midnight
- Level 3Comparing two spans

What Grade 4 time work should cover
By Grade 4 children are expected to convert between units of time, read and use the 24-hour clock, and solve duration problems that span hours and minutes. These sheets take those three strands one per page. Writing an answer as "2 hours 40 minutes" rather than "160 minutes" is a small change with a large payoff: it forces the child to hold two units at once and stops sixty from being treated as if it were a hundred.
The 24-Hour Clock sheet is where most of the confusion lives. The rule itself is short — after midday, add twelve to the hour — but reading 16:05 fluently as five past four in the afternoon takes practice. Its opening level, Afternoon and evening times, stays where the notation is unmistakable; Morning, noon and midnight then brings in readings like 02:45 and 07:45, where the leading zero is the whole point; and Calculate on the 24-hour clock finishes with journeys that depart and arrive on 24-hour readings.
Durations that cross noon and midnight
Crossing noon and Crossing midnight, the upper levels of Later Times, are the classic exam trap. A film that begins at 10:35 am and runs for three hours and fifty minutes does not finish at 14:25 in the child's head unless they have noticed that the clock passes twelve on the way. The safe method is to break the duration at the boundary: work out how long until noon, subtract that from the total, then add what is left to 12:00. Midnight works the same way with 12:00 am as the boundary, and Elapsed Time in Hours and Minutes runs that same crossing in reverse on its own Crossing midnight level.
Ask for the am or pm marker on every answer, and treat a missing one as an incomplete answer. This is also the right moment to talk about why timetables use the 24-hour clock at all: it removes the ambiguity that makes these questions tricky in the first place. If a child can explain that, the notation stops feeling arbitrary.
Frequently asked questions
▸What time topics are covered in Grade 4?
Durations written in hours and minutes, reading and calculating with the 24-hour clock, and adding a length of time to a clock time so that it crosses noon or midnight. Elapsed Time in Hours and Minutes, The 24-Hour Clock and Later Times take those three in turn, each on its own sheet.
▸How do you convert to the 24-hour clock?
Morning times keep the same hour with a leading zero, so 7:45 am is 07:45. From 1:00 pm onwards, add twelve to the hour, so 4:20 pm becomes 16:20. Midnight is 00:00 and midday is 12:00.
▸How do you work out a duration that passes midday?
Split the duration at 12:00. Find how long it is from the start time to noon, take that off the total, and add whatever is left to 12:00. A start of 10:35 am with 3 hours 50 minutes gives 1 hour 25 minutes to noon and 2 hours 25 minutes after it, so it finishes at 2:25 pm.
▸Why should answers be in hours and minutes rather than minutes?
Because that is how timetables, journeys and school days are described, and because it stops children treating an hour as if it had a hundred minutes. Grade 3 sheets answer in minutes; Grade 4 is the year the two-unit answer becomes the standard.
▸Can I use these sheets for timetable practice?
Yes. The Calculate on the 24-hour clock level of The 24-Hour Clock is built from journeys and events with a start time and a duration, the start time and the answer both on 24-hour readings, which is the same reading a bus or train timetable asks for. Press Shuffle for a fresh set at the same level.
